This invention relates to an ice' scoring'machine, as described? in thepresent specification and illustrated in the accompanying drawings whichform part of same.

The invention consists essentially of the novel: features pointed outbroadly'and spe cifically in the claims for novelty following adescription containing an explanation in detail of an acceptableform ofthe inveni.

The objects of the invention are to build an ice scoring machine ofsimple,-durable and economical construction; to effect all 'aossibleeconomy ofspace by making avery compactand complete machine; to make theoperation in such a machine as simple and reliable as possible; andgenerally, to improve upon existing'icescoring' machines.

In the drawings, Figure 1 is a'front elevation of the machine.

Figure 2 is a section on line 2"2 in. Figure 1. v g I I Figure 3 is afragmentary side elevation of the sprocket chain showing thespecial-link and bridge.

Figure i is a top plan view of'Figure 3.

Figure 5 is a fragmentary view showing the ice block feeding or shiftingmeans.

Like numerals of reference indicate corre sponding parts in the variousfigures.

Referring to the drawings, 10- is the frame of the machine; the frame ismadc'of two end upright members 11, preferably castings, rigidly securedin their spaced lrelation'by spacers '12. and 18, and by thelongitudinal members or beams 14: which are positionedin the axis of themachine. 17 17 and 18 are sprockets rotating in the end members 11, eachof the sprock-ets 17 rotating with the gear 19' meshing with the gear 20rigidly mounted on the horizontally-arranged shaft 21: the shaft 21rotates in suitable bearings 21*. 22 are sprocket chainswound around,

the sprockets, as best shown in Figures 1 and 2; the sprocketsare'dlsposed in a rectangular arrangement, as best shown in Figure 2. sothat the sprocket chains travel in a substantially rectangular path.

23 is a motor mounted on th-e'bracket 24 and rotating thehorizontally-arranged shaft 25, on one endof which is rigidly mountedthe pulley 26. 27 is a pulley rigidly mounted on one end of theshaft21;, and 28 is a belt wound around the pulleys 27 and 26. '29 are thescoring saws or elements rigidly n ountecl' on tli shaft in. anySuitable way.

By operating the motor, the saws are rotated, thesliaft 21 also rotated,turning the gears and the sprockets 17 and therefore propelling thesprocket chains 22 man endless course or path around the sprockets.

Pivotally suspended from the sprocket chainsQQ' are the elevators,cradles or carriers 30 by which the ice block is carried; each elevatorrises vertically to bring one face of the block in contact with therevolving saws, thus scoring that face, and later descends to bringtheopposite or unscored face of the block in contact with the saws to.

score the last-mentioned,face of-sa-id block; The elevator is formedsubstantially as shown, having the spaced longitudinally-arrangedmembers 31 secu-redto the-tension members or supporting arms 32 bymeansof the bolts 32. Each ofthe arms 32 is formed withsuitable eye33topivotal'ly connect the armto the stud or pin 34 of the sprocketchain, specially-formed link 35'.

The link'35 rigidly carries the bridge member 36' which is approximatelytwice as long the distance between the upper sprockets 17 and 17 thusforming a bridge between these sprockets and, taking the load or weightof the: elevator and ice off the chains when the links 35 are in anyposition between sprockets, or in other words, when the elevator' istravelling horizontally between the sprockets 17] and 17 37 are crossmembers rigidly carried by the members 31 and spaced at a distance lessthan thel'ength of the ice block; near each end of the cross members aresharp pins or points, 38, forming 'supports for the ice, and thereforedigging into the ice block and preventing it from slipping.

The elevators are disposed along the chains so as to balance, as much aspossible, the weight of one with that of the other.

40 are; bars vertically arranged by bolting same to the bars 12",ancl13at a distance apart less than the length of the block of ice,

these bars formingslides or guides for the block as it travels upwardlyand downwardl, durin the scoring 6 eration or in other words,constraining the movement of the block during scoring to two planesparallel, with the chains 2'2.

: 411 are af pairv ofu shaped irons suitably secured to thebeamslhforming stops checkmg the motion ofthe, ice block as it is pushedor fed'into the machine rior to scoring, and I a f rm ng g des wit theguides t0,

46 are horizontallyarranged bars bolted to the U-irons 41 and laid atright angles to the axis of the machine, one end of the bars being -bentdownwardly and inwardly as at 47; 43 is a plate supported by the angleirons 42 which are secured to the end castings 11 of the frame 10, thisplate forn'iing a table for the ice block as it is slid endwise into thefeeding position, and also forming with the bars 46 the meansofsupporting the block before it is engaged andlifted by the risingcradle 30 forthe first scoring operation. The plate 43 and bars 46 arespaced from one another to provide a clearance 48 for the passage of thebars ill of the cradle 30. Bars 5-.l.haing the turned down ends 54 arecarried by the floor and spaced opposite the bars 46, thus guiding thecradle bars 31 into the clearance 48. An angle 44 having the turned outend is preferably provided on the plate or table 43, so as to guide theice when slid into feeding position in front of the machine; 50 is asuitable stop for arresting the motion of the block when pushed in overthe table, this stop also determining the position of the block fromwhich. it is to be fed into the machine.

53 is a suitable table secured to the frame. as with angles 55; asuitable slide is provided to elevate the block from the cradle, afterscoring, and allowing it to slide down onto the table 53, this slide andtable forming the ice delivery means of themachine. The slide may beformed with metal-shod wooden wedge-shaped blocks 56 and 57 secured tothe bars 46 and plate 53, respectively, these blocks being spaced toprovide a clear ance 58 for the passage of the cradle bars 31 as thecradle travels downwardly. 51 and 52 are guide bars vertically arrangedand secured in position in any suitable way; in the drawings, the bars51 are shown bolted to the cross bar 51 which is rigidly secured to oneof the beams 14, 60 being an angle brace securing the lower ends of thebars 51 to the longitudinally-arranged bar 61 carried by the U-bar 41;the guide bars 52 are shown secured to cleats 62 carried by the braces13 and also suitably fastened at the beyond the angle 44 of the table43, slots 68 being provided through the angle 44 to form a passage forthe ends of the arms as these are swung outwardly into operativeposition; the operative position of the arms 67 or lever 63, isdetermined by the engagement of the arms with the angle 44, or in anyother suitable way.

recesses As the chains describe a substantially reetangular path, risingand loweringin vertical parallel planes, it follows that the clearances4S and 58 must be verticallybelow the pivotal point of the cradle on thechain.

Operation: As already explained, the operation of the motor rotates thesaws 29 while rotatingthc shaft 21 and propelling the chains 22. As thechains are'propelled, in the direction of the arrow (Figure 2), thecradle describes a rectangular path. The iniscored ice block is pushedupon the table 43, sliding against the angle 44 until it is arrested bythe stop 50. The lever 63 is then pulled away from the machine. the arms67 slidahly engaging one face of the block and sliding same overthetable 43 and onto'the bars 46 until it comes in contact with theirons 41. The block is now in a position to be engaged or lifted by thecradle as it travels up through the passage 48. One face of the block isscored as the cradle travels upwardly; as the cradle travelshorizontally between the sprockets 17 and 17", the bridges 36 take theweight ofthe cradle and ice. off the chains and transfer same to thesprockets; as the cradle descends, the other or unscored face of theblock is scored, and as the cradle passes through the. clearance 58, theblock becomes supported by the slide and tinally slides out of themachine onto the ta.- ble 53. I i

If thetables 43 and are made level with the floor, a trough is madeinto'the floor below the machine frame to provideclearance for thepassage of the cradle as it swings under the machine.

It is to be understood that the invention is not confined to theparticular construction shown. nor to the use of two cradles. Similarly,the invention is not confined to the use of a table 53, or of a table43, since the ice could be slid over the floor and into the machine anddischarged at the delivery side onto the floor.
